1. Before pumping begins, the operator of the hose communicates well with the operator of the pump. The bending radius of the front hose should be greater than 1m.
2. The hose of the concrete mixing pump should be fixed and solid. Do not bend the hose of the mixing transfer pump to avoid the hose explosion. This is also one of the reasons for the blockage of the mixing pump pipe, when the pipeline is blocked, after the treatment of pumping, the end of the soft section will swing rapidly, the concrete may be sprayed momentarily, the staff shall not be near the hose.
3. Pay attention to standing at the corner of the building when operating the hose of the concrete mixing and conveying pump, because the hose is soft, shaking or concrete injection may occur when pumping concrete, which may lead to the risk of falling.
